BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Viola, botanically known as Viola×williamsii and hereinafter referred to by the name ‘Flovellavyel’.

The new Viola plant is a product of a planned breeding program conducted by the Inventor in Foxley, Norfolk, United Kingdom. The objective of the breeding program was to create new outwardly spreading Viola cultivars with large flowers and attractive flower coloration.

The new Viola plant originated from a cross-pollination made by the Inventor in May, 2001, in Foxley, Norfolk, United Kingdom, of a proprietary selection of Viola×williamsii identified as code number USAHIL-2, not patented, as the female, or seed, parent with a proprietary selection of Viola×williamsii identified as code number USABVZ, not patented, as the male, or pollen, parent. The new Viola was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Foxley, Norfolk, United Kingdom in May, 2002.

Asexual reproduction of the new Viola plant by vegetative cuttings in a controlled greenhouse environment in Foxley, Norfolk, United Kingdom since September, 2002, has shown that the unique features of this new Viola plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Viola have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Flovellavyel’. These characteristics in combination distinguish ‘Flovellavyel’ as a new and distinct cultivar of Viola:

-   -   1. Mounding and outwardly spreading plant habit.     -   2. Freely branching habit.     -   3. Early and freely flowering habit.     -   4. Long flowering period.     -   5. Large pale violet and yellow-colored flowers.

Compared to plants of the female parent selection, plants of the new Viola differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Viola are not as open in plant habit as         plants of the female parent selection.     -   2. Plants of the new Viola flower earlier than plants of the         female parent selection.     -   3. Plants of the new Violet have larger flowers than plants of         the female parent selection.     -   4. Plants of the new Viola and the female parent selection         differ in flower color as plants of the female parent selection         have blue-colored flowers.

Compared to plants of the male parent selection, plants of the new Viola differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Viola are not as compact as plants of the         male parent selection.     -   2. Plants of the new Viola are more outwardly spreading than and         not as upright as plants of the male parent selection.     -   3. Plants of the new Viola have larger flowers than plants of         the male parent selection.     -   4. Plants of the new Viola and the male parent selection differ         in flower color as plants of the male parent selection have         yellow-colored flowers.

Plants of the new Viola can be compared to plants of Viola ‘Flovellempl’, disclosed in a U.S. Plant patent application Ser. No. 12/290,132 filed concurrently. Plants of the new Viola differ primarily from plants of ‘Flovellempl’ in flower color. In addition, plants of the new Viola have larger flowers than plants of ‘Flovellempl’.

Plants of the new Viola can also be compared to plants of the Viola×williamsii ‘Sunviobuho’, disclosed in U.S. Plant Pat. No. 16,557. In side-by-side comparisons conducted in Foxley, Norfolk, United Kingdom, plants of the new Viola and ‘Sunviobuho’ differed in the following characteristics:

-   -   1. Plants of the new Viola were more mounding than plants of         ‘Sunviobuho’.     -   2. Plants of the new Viola had larger flowers than plants of         ‘Sunviobuho’.     -   3. Plants of the new Viola and ‘Sunviobuho’ differed in flower         color.
